Patented New, 191?? means for actuating the bottle distributingmechanism. a 1

Fig. 5 is a sectional view taken on the line 55 of Fig. 3.

Referring now more particularly to the accompanying drawings, 5designates each of the side walls of an elongated annealin oven 6designates the bottom Wallthereo and designates the top wall thereofwhich terminates short of the side walls ,at the receiving end of theoven, the space between the end of the topwall and the ends ofthe sidewalls being closed by a journal plate 8 for the bottle distributingmechanism.

The. bottom 6 of the oven carries a longitudinal pair of tracks 9 forthe wheels 10016 aseries of'bed trays and each of these-bed trayscomprises apair of longitudinalw-heel carrying sills 11 and a pluralityof ,transverse floor plates 12 preferably formed, of

sheet iron and having their edgeportions bent downwardly, aS shoWn--more: particularly at 13 in Fig. 1 to-seat into notchesyoi the sills 11whereby to'stifi'en said plates".

The detachable connection of the trays is procured by lugs 14: on therear endsfiof. the side sills engageable in sockets 15 of-the forwardends of said sills, and thus aslthe bed trays are moved through theoven, the

endmost trays may be readily connected and disconnected to afi'orda'continuous movable bed inthe oven. For procuring movement through theoven of the series of trays thus connected, each tray is provided witharentral longitudinal toothed-rack 16 'andythese racks are successivelyeng'age'able' with a gear 17 carried by a shaft 18 journaledij' in thebottom 6 of the furnace andin a bracket carried by a transverse beam,l9' zthereheloyv.

The racks areheld inmeshGWith the gear by an idle pulley 20 mounted0n=the bottom 6 at the opposite sides of the racks;

,For feeding and distributing bottle 'e oven, a chute 21 is provided atone ide'bf the feeding end of the oven and thischutemay be fed in anymanner. procurifigia' ositive movement of bottles -tliereoI -a suite is:con

For

procuring successive rotative'step movements Iof this wheel as bottlesare supplied thereto,

a wheel 25 is fixed on the shaft 23 above the top plate 8 and carries adouble series of ratchet teeth, one series being engageable by a feedawl 26"carried by a lever 27 intermediate y pivoted on the shaft andhaving its other end in link connection with the stem 28 of a piston29'disposed in a cylinder 30 from which apipe 31 extends to a valve 32"disposed adjacent the discharge end of the chute, this valve beingconnected in turn by the pi e 33 with a suitable source of compressedair. The valve is operated by a spring urged roller carrying stem 34rojecting therefrom into the path ofthe ot- .tles as they are dischargedfrom the chute and thus as ,the bottles successively move from thechute, the valve will be 0 ened to impart successive rotative steps to te wheel carryingshaft through the medium of the cylinder andpiston andthe pawl 26. For stopping the shaft subsequent to each rotative impulse,an arcuate pawl 35 is pivoted on the plate Sand is resiliently urged toen- I gagement with the other ratchet teeth of the wheel 25 by a springurged link. 36 connected therewith. The lever 27 carrying the pawl 26 isresiliently urged to initial position by a spring 37 on the piston stem28, and air is piston by any suitable means and preferab y by providingthe valve 32 of a two-way type normally open with respect to 'thecylinder, the structure of this valve being not shown, as any preferablyconventional valve may be used.

Thus upon a plurality of bottles being fed into'the oven, they will bedisposed along the inner side of the periphery of the wheel, as shownmoreparticularly m Fig. 3. To

' clear the .bottles fromthe wheel when an inder 42 from whence a pipe43 extends to a arcuate series thereof has been fed into the oven, anarcuate sweep 38 is provided which normally extends transversely overthe wheel, and which is carried by a vertical shaft 39 at theside of thewheel opposite the chute 21, thisfshaft being journal'ed in the topplate 8 and in the transverse beam 22. For actuating the shaft to causean inward sweeping movement of the sweep 38 a crank-arm 40 is providedat its upper end which is in link connection with the piston stem 41 ofa cylvalve44 connected also with a suitable source of air pressure 45,this'valve being operable by a roller carrying spring urged stem 46which projects into the rotative path of the bottles carried by thewheel 24, and thus upon engagement of the bottles therewith procures t eswinging movement of the sweep to clear the bottles from the wheel anddispose them in a substantially angular line on the movable bed, itbeing noted that the action of the '-s eep is comparatively rapidinasmuch as it must return to initial position prior to the engagementof subsequent bottles with the wheel. In view of the very slow feedingmovement of the bed of the oven, the successive rotative movementsof thewheel serve to retain the bottles in the pockets thereof, particularl byreason ofthe forward inclination of the wheel fingers with respect totheir direction of travel. For

returning the' sweep in a rapid manner, a

relativsly strong spring 47 is connected with the era -'arm 40 thereof.

For closing the receiving end of the oven, a hood 48 is hinged to oneside wall thereof above the movable bed trays and this hood comprises anarcuate vertical wall providing clearance for the wheel.

As-the bottles arefed into the oven from the molding machine they are ata considerable heat, and to provide for a proper heating of thebedtraysprior to engagement of the bottles thereon, a compartment isformed in the forward end of the furnace by the rovision of a partitionwall 49 below the ottom 6 of the oven and disposed in this compartmentare supply coils 50 which may form part of any heating means, the bottom6 of the oven immediately'above the compartment being provided withseries of apertures, and it is noted that the heatin of the bed travs isfacilitated by reason 0 the relatively thin metallic floor platesthereof. The rotation of the shaft 18 which carries the gear wheel 17for procuring feeding movement of these bed trays is procured throughthe medium of a worm gear connection 52 with a countershaft 53 rojectinoutwardly of one of the side wafils 5 an driven in any suitable manner.

While I have shown and described a ferred embodiment 'of my invention,1t is obvious that to meetidifiering conditions of use, various changesand modifications of structure may be resorted to without de arting inany'manner from the spirit 0 my invention.

I claim:

1. In a device of the class described, the combination of a movable bed,a wheel mounted over said bed andprovided with a 2. In a devlce of theelass described the combination of a bed, a wheel connected with thecrank arm,
